TrustCaptcha for React — GDPR-compliant, privacy-first CAPTCHA

Protect websites and apps against bots and spam with a privacy-first, EU-hosted CAPTCHA solution.

What is TrustCaptcha?

TrustCaptcha combines proof-of-work, an AI bot-score and custom security rules to stop automated bot abuse — without image marking or puzzles

Key perks:

• Privacy-friendly & GDPR-compliant – data processed exclusively in Europe
• No visual challenges – users never label images or solve quizzes
• Fully themable widget – matches any brand and design and improves your user flow
• Conversion-safe – near-zero user drop-off compared to legacy CAPTCHAs

Read the full TrustCaptcha product overview for technical details and the security concept.

Get started

1. Create an account: sign up / sign in.
2. Choose a CAPTCHA: pick an existing one or create a new one.
3. Embed the widget: implement the TrustCaptcha widget into your website or app.
4. Validate result: validate the CAPTCHA verification result in your backend.

    <div>
      <form>

        <!-- your input fields -->
